An electronic warning system has been developed to restrict cattle
access to sensitive areas. Radio receivers on special ear tags attached
to cattle are triggered when they approach an "electronic fence,"
the boundaries of which are determined by the position of transmitting
stations. The influence of the technology on cattle health, physiology,
and behavior have been examined. Technology for this system is currently
being refined, with emphasis on reducing the weight and size of
the ear tags.

Cost: BMNRI-60K; Grants-158K; Total-401K
